Taking a caravan out after six months or more of storage isn’t as simple as hitching up and heading off. Systems that sit unused can degrade quietly — and the first signs often show up on the road or at the campsite, not in the driveway.
Recommissioning is about safely bringing the caravan back into service, checking every system that may have deteriorated while idle.
This guide walks through what to check, what to test, and what to fix before your first trip back.
What You’ll Learn
- Why recommissioning matters after long storage
- The order systems should be checked
- Common issues caused by inactivity
- What you can safely DIY
- When professional inspection is smart
This guide is suitable for all caravan owners, especially after seasonal or long-term storage.
Why Recommissioning Is Important
During long storage:
- Seals dry out
- Batteries discharge and sulphate
- Gas systems collect air and debris
- Water systems stagnate
- Tyres flat-spot and degrade
Recommissioning reduces the risk of breakdowns, leaks, and safety issues.
Step-by-Step: Recommissioning a Caravan After Storage
1. External Walkaround and Visual Inspection
Start with a slow, methodical walkaround.
Check:
- Roof, walls, and seals
- Windows, hatches, and doors
- Signs of water ingress or damage
- Evidence of pests or nests
Address visible issues before powering anything up.
2. Tyres, Wheels, and Running Gear
Before towing:
- Check tyre pressures
- Inspect for cracking or flat spots
- Check wheel nuts
- Inspect suspension and brakes visually
Tyres age even when stationary.
3. Battery and Electrical Systems
Long storage is hard on batteries.
- Reconnect batteries if disconnected
- Check voltage before loading systems
- Test 12V and 240V circuits
- Replace batteries that won’t hold charge
Low voltage causes appliance faults.
4. Gas System Safety Checks
Before lighting anything:
- Inspect gas hoses for cracking
- Check regulator condition
- Reconnect bottles carefully
- Test other gas appliances first
Air in gas lines after storage is normal.
5. Water System Recommissioning
Water systems should never be trusted blindly after storage.
Steps:
- Inspect tanks and hoses
- Flush fresh water tanks
- Clean or sanitise if needed
- Run all taps (hot and cold)
- Check for leaks
Expect blocked aerators or filters initially.
6. Appliance Testing (One by One)
Test appliances individually:
- Fridge (240V first, then gas)
- Hot water system
- Stove and oven
- Air conditioner
Avoid running multiple systems at once initially.
7. Interior Checks
Inside the caravan:
- Look for mould or odours
- Check soft furnishings
- Inspect cupboards and under beds
- Remove moisture absorbers
Ventilate thoroughly before travel.
8. Short Test Run Before a Big Trip
Before committing to a long journey:
- Tow the caravan locally
- Test brakes and lights
- Recheck fasteners and wheel nuts
- Confirm appliances work under load
Small test runs reveal issues safely.
Common Problems After Long Storage
- Flat or failed batteries
- Blocked water filters
- Gas ignition issues
- Fridge faults due to air or dust
- Leaks from dried seals
Most are minor if caught early.
Common Mistakes to Avoid
- Powering everything up at once
- Skipping water system flushing
- Assuming tyres are fine “because they look okay”
- Ignoring musty smells
- Heading straight on a long trip
Slow recommissioning saves time later.
When to Call a Professional
Professional checks are recommended if:
- Storage exceeded 12 months
- You suspect gas or electrical faults
- Water damage is visible
- Appliances fail initial testing
A pre-trip inspection is cheaper than roadside repairs.
Key Takeaways
- Long storage affects every system
- Visual inspection comes first
- Batteries and water systems need care
- Gas systems should be checked calmly
- Test locally before long trips
